Paul what is the current Width of the Rearend
from the Wheel Mounting Pad/Face of the Drum or Disc Brakes on the one side to the other side ?

My comment was assuming Paul was using a starting point of a stock-width 60" rear, Greg. To run those particular rear wheels, a rear end of approximately 56" wide will be needed, if there's no minitub performed.
Question: will a 9" that narrow have room for the oem control arm mounting points?

Clint that is what I would worry about the most

I do not think so but Big Gear Head would know for sure

I think I remember reading one of his Posts
that said if Shorting the 60" Rearend by more than a 1" or 1.5"
would result in moving the Shock Mounting plus then problems
with lining up the Lower Contrl Bracket Mounts on the Body/Frame
and on the Rearend Housing since they would have to be also relocated

I Could be wrong tho

I think if his 9" Rearend is 60" Wide now and in the car

I would not send to anyone to Shorten it

I would just buy Wheels with the right BackSpacing
easier and maybe cheaper in the long run

I agree 100%, Greg. Wheels with oddball offsets can be hard to sell, should one decide to change wheels,later.

Re: how much space between your wheel well and rear tire do you need.?

Rear is 58 total. with wheels and tires it's 73. between the quarter wheel wells it's a hair under 74.
Close fit but the tires will fit in the quarters as is.

After I put it all back together i'll have a more exact mesurment though.

Re: how much space between your wheel well and rear tire do you need.?

Finally got time to mount the wheels to the frame... Actual width is 72 1/4" from outside of the tires.... Wheel well to well is 73 3/4".
Shock to drum is 2" inches and there's 1 1/2" between the frame and tire.

So IF? I can centre the body perfectly. and trim the lip a bit I should be ok with out touching the rear end.

I'll find out this weekend...

Re: how much space between your wheel well and rear tire do you need.?

On a 67 with stock-width 60" rear end, an 18x10 w/5.75" backspace is what I would recommend for best fit. A 58" width rear would therefore need 4.75" backspace on those 18x10's.
IMO, you're going to have clearance issues with only 4" backspacing.

So by your math, take 1.5 inches out of the rear end and i'm good. I'm 2 inches from the drum to the shock on either side so that shouldn't be an issue.

but for now I'll wait till the body is back on.... and go from there.

Re: how much space between your wheel well and rear tire do you need.?

Paul you have to understand that by narrowing that current 9" Ford Rearend Housing
you will have to relocate the Housing Brackets further inward on the Housing

If you look at your First Pic you can see where the Ends are Welded onto the Housing
and see that there is little/no space to further Shorten the Rear Housing
unless you move/relocate the Lower Control Brackets inward IMHO
which will result in the Housing Brackets not lining up with the Frame/Body Brackets

How did you measure the Width of your current 9" Rearend ?

as if you measured it like you did in the first Pic from the Back of the Brake Drum
to the other Back of the Brake Drum that is why you come up with 58"
OR did you take off the Wheels/Tires on each side and measure from
the Front/Face/Wheel Mounting Pad of the Brake Drums on one side to the same on the other side ??

Just trying to make sure we are looking at the right measurements etc. for us to advise you correctly !

Re: how much space between your wheel well and rear tire do you need.?

Paul, it looks like the best option would be to send your rear wheels back to Billet Specialties and have them change the backspacing so they will fit your car.
As Greg explained, you really shouldn't narrow that rear end any further. It's fine the way it is. Get the wheels corrected and you should be good.

I get what you mean, There isn't much room for change on the rear end.
I measured it with the wheels off, Outside Drum to drum to get 58"

Once I get the body on I can get exact numbers on how much room I have to the wheel well. It's gonna be close but it looks like I should have a hair over half an inch on each side.

Re: how much space between your wheel well and rear tire do you need.?

Gotcha, so you had it narrowed 2" / 1" on each side !

Like Clint says a 10" Wide Wheel with a 4.75" BS would likel;y work the best for your car
with the current Rearend Width of 58"

You should be good to go with a 1/2" clearance on the Inside/Frame and the Outside/Inner FenderLip

I have that much Room/Space on my 67 with a 8" Wide Wheel x 15" Dia with a 4.5" BackSpace
that has a Stock 60" Width Rearend in it
